Abstract

Network controlled system will always experience some delays in communications, and how to improve its stability is of great importance for industry applications. In this paper, one novel method of delay compensation by utilizing digital redesign is proposed. First, analog controller is designed for the delay free system, and then the delay compensation algorithm is modulated through A/D conversion. In addition, this method can deal with delay variations by adjusting PAM controller period. The proposed methodologies have been testified through MATLAB/Simulink, and the simulation results effectively confirmed its theoretical correctness.
